I'm purchasing a notebook, and I have a question about which processor would be best for me. I'll be using it for web and graphic design, as well as music/movie/photo storage and editing. I'll most likely get 2.0 gb of memory with Media Center 2005 and a 100 gb hard drive.
There are several processors to choose from, so here is my question: Is there a notable performance difference between an Intel Core Duo T2250, an Intel Core 2 Duo T5600 and an Intel Core 2 Duo T7400? I'm leaning towards the T5600 but I would like an expert opinion.
Also, as a secondary question, how easy is it to upgrade the memory in a laptop? If I decided to get 1.0 gb for now, would it be easy to change it to 2 gb later?
